5-16 Removal and Replacement Procedures
5.12.2 Active Heat Sink (P55C/200)
1. Perform preparation procedures (Section 5.4).
2. Remove the system unit cover (Section 5.5).
CAUTION:
When replacing a Pentium processor, you must release the heat sink retaining clip before you
pull the ZIF socket handle. This clip engages the processor socket to hold the heat sink in place.
!
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the internal system components
to cool before touching.
3. Remove the heat sink fan plug 3 from the socket on the system board.
4. Release the heat sink retaining clips 2 from the tabs on the ZIF socket.
5. Lift the heat sink 1 off the ZIF socket.
6. Release the original processor from the socket by pulling the handle 6 on the ZIF socket out
and upward.
✎
The handle on the ZIF socket in your computer may not look identical to the
handle shown in the drawing. All handle types perform the same function.
6. Lift the processor 5 out of the socket.
Figure 5-13.2.
Removing the Microprocessor from the System Board
CAUTION:
When replacing the processor, be sure that the clipped corner of the processor (location of
Pin 1) is aligned with the triangular area of the ZIF socket (hinged corner). Failure to do so could result in
burning out both the processor and the system board.
